Hey guys! I ride my Lupo 30KM over the highway every day. As it rains a lot at the moment, the car (black) looks particularly from the back like shit because of all the water swirls. I polished the car thoroughly before the winter and sealed it! No matter what my question: Does it hurt the paint or car if I would wash the car with a high pressure cleaner for 1 or 2 minutes? The windows and everything gets dirty very quickly, so it is really necessary the car I want to keep my baby standing clean 😛 Thanks for your opinions
